The Challenge: During peak combat—especially in 3-player squad engagements—the original HUD suffered from severe information overload. Critical data (enemy movement, ally health, ultimate ability status) competed for visual attention with non-essential stats (ammo count, player position on mini-map).
The Methodology: We implemented a 'Contextual Priority' engine. This isn't a simple toggle; it's a rule-based system. When an enemy is targeted and within 50 meters, their health bar and threat indicator become 100% opaque. All other UI elements fade to 30% opacity. When the target is lost or the player is safe, essential survival stats return to prominence. This reduced cognitive load by design.
The Outcome: A/B testing over two seasons showed a 15% increase in player session length. Player feedback noted a reduction in 'frantic fumbling' during firefights. The revenue impact was secondary to the retention metric, which is our core KPI for UI performance.
